Re: Number of dresses for wedding
^ A little of both. FIL didn't have a lot of input for clothes, but he always says that he feels women look best in saris. My MIL wears them often -- she has all sorts -- casual and formal. So she has a selection for any occasion.
I still haven't actually tried tying one on my own. With mom and MIL so close by, I've been spoilt :D.
